Just to add my two cents into this discussion, I was told Unofficially by an attorney that purchasing the domain name for your product may stand up legally if someone else starts using your product name AFTER the website domain was purchased and a website featuring your product was created. So start a small website with the name of your product and that may provide some protection if you cannot provide a trademark at this time

Thanks very much. I do have the name as my domain. I've checked into a trademark and am going to register it. I really wanted to get the product out there and see if there would be a response to it before I put too much money into it.
